RS-232 Command Set Reference
communicate with the host device, it is necessary to set the Model 186 to the identical
baud rate of the host device.
RS-232 Command Set Reference
All commands sent to the Model 186 are processed and the Model 186 responds with
a return value (if applicable) and termination. If the command is invalid, the Model
186 will respond with an error code (see the
Error Codes
section). All return values
including error codes are terminated with
<CR><LF>
(i.e. a
carriage return
followed
by a
linefeed
). For those commands that do not return a value, the Model 186 will
return the
<CR><LF>
termination only.
Commands for controlling the units of measurement
The CM command sets the units of measurement to centimeters and the INCH
command selects inches. The PERCENT command sets the units of measurement to
the percentage of active sensor length that is immersed in liquid. The units of
measurement selected through the RS-232 interface are controlled independently from
the units mode toggle switch used for controlling the front panel display. The default
units are centimeters when the Model 186 is first powered on. The last unit command
remains in effect until the unit is powered off. The setting is not saved in permanent
memory. The UNIT command returns a one character value (and termination)
indicating the current units—C for centimeters, I for inches, or % for percentage.
